Can you read the same packet from rf230 buffer twice and compare ?

Very interesting. The RF230 should not have done that: in section 8.2.4 it says:

Hi,
I have a simple test where one node broadcasts packets and it is
received by multiple nodes. I noticed that I was occassionally receiving
some corrupted packets. The packets were transmitted correctly because
one of the other nodes received the packet correctly.
